BOBBIN -WINDI1\TG MACHINE.

Specification of Letters Patent.

Patented Feb. 19, 1918.

To all whom it may concern:

Be it known that I, EDWARD E. BRADLEY, a citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Bobbin- Winding Machines, of which the following is a specification.

In bobbin winding machines as heretofore constructed, the take-up bobbins are held in a swinging hanger so that the weight of the hanger will hold the bobbins down upon their driving drums thus giving the necessary tension to draw the thread.

In machines of this character, the bobbins are run upon a loose gudgeon and when it is desired to dofi the bobbins it is necessary to remove the bobbins and their loose gudgeons from the hanger. This is an awkward operation and frequently allows the bobbins and their gudgeons to drop onto the floor thereby causing much delay in the operation of dofling.

The object of my invention is to provide a structure in which the loose gudgeon is obviated and, at the same time, retain the downward pressure on the gudgeon. To accomplish this, I make each hanger in two members, in one of which members one end of the gudgeon is rotatably but not removably mounted, the other end of the gudgeon being arranged to be brought into and out of its bearing in the other member of the hanger.

In the operation of windlng, 1t 1s frequently necessary to piece up the ends of the take-up bobbin and to accomphsh thls I have provided a structure in which-the two members of the hanger may be raised together to lift the bobbin from its drivlng drum.

When it is desired to dofi' the bobbm, I have provided means for further lifting the member of the hanger which carries the gudgeon and bobbin away from the other member of the hanger a suficient distance to remove the bobbin from the gudgeon.

A practical embodiment of my invent1on is represented in the accompanying drawings, in which Figure 1 represents in end elevation my improved hanger attached to the longitudinal bars of the winding machine, the parts being in the positions which they assume when the bobbin is resting on its driving drum,

F g. 2 is a top plan view of the same,

Fig. 3 1s a view of the hanger and its ad-- acent parts taken from the opposite end from Fig. 1, the parts being shown in full 11nes in the positions which they assume when the bobbin has been lifted for piecing up the thread, the position of the parts as shown in Fig. 1 being shown in dotted lines in this figure,

Fig. 4; is a view similar to Fig. 3 with the parts in the positions which they assume when one member of the hanger has been ralsed from the other member to permit the doiling of the bobbin, and Fig. 5 is a front view of the hanger and 1ts adjacent parts with the parts in the positions shown in Fig. 3.

The longitudinal bars of the winding machine are denoted by 1, to which the supporting bracket 2 is clamped in the usual manner by the shoe 3 and bolt 4. The bracket is provided with uprising sides 5, 6, and from the base of thebracket, arms 7 8, pro ect in opposite directions. As all of the hangers and their operating parts are the same, I will describe only one of said hangers and its operating parts herein.

An auxiliary bracket 9 is secured to the uprising side 5 by bolts 10 by means of which the hanger as a whole can be alined for the purpose of squaring the axis of the bobbin with respect to the axis of its driving drum 11. This auxiliary bracket 9 is provided wit-h an axle pin 12 on which are loosely hinged the inner ends of the arms 13, 14, of one member of the hanger and the inner ends of the arms 15, 16, of the other member of the hanger. The other end of the arm 14 of the hanger is provided with a cross piece 17 connecting it with the arm 13 at a distance outwardly from the hinged end of said arm. I

Across piece 18 connects the outer end of the arm 15 with the arm 16 at a distance outwardly from the hinged end of the arm 16.

The two members of the hanger overlap each other so that they may be moved together during a portion of their swinging movement by a swinging operating 7 means, as will hereinafter more fully apbearings being provided in a spring actuated latch 24 hinged at 25 to the-said arm 13 and held yieldingly at the limit of its.

inward movement 'by a coil spring 26 against a stop 27 on the-arm 13. v

A spring 28 connects the arm 16 with the auxiliary bracket 9, which spring tends to press both members of the-hanger downwardlyto bring the bobbin19 into driving engagement with its drum 11. This is accomplished because of the overlapping of the arms 14, 15, of the two members of the hanger. I

. An arm 29 on the auxiliary bracket 9 is provided with an adjustable screw 30 act-' ing as a stop for limiting the upward-movement of thehanger which carries thegudgeon 20. V ,7 The spring 28 is so located that'when the said gudgeon carrying member of the hanger is in its'ful'ly raised position, the

spring will hold it in this position bythe swinging ofthe axis of the spring to a point above the axis of the said hanger member. p

An operating lever 31 is pivoted at 32 -to the arm 7, Which lever is provided with two laterally projecting pins 33, 34; The pin 33 is arranged to be brought into operative engagement with the under side of the arm 13 for moving the arm and thereby both; members of the'hanger upwardly as the, lever is moved forwardly. The pin 34 is arranged in position to engage the cam surface 35 of the spring catch 24 as the lever is swung forwardly for the purpose of releasing the free end of the gudgeon 20 from its bearing in the said catch 9A to permit the] further upward movement of the gudgeon' carrying member for the purpose of dofling the bobbin.

In operatlon, assuming the parts to be in the position shownin Fig. 1, with the hanger dropped down to bring the bobbin into its driving engagement withthe drum and the operating lever in. its raised or released position, the forward swinging movement of the lever will, because of the engagement of its pin 33 with' the under side of the arm 13, lift both members of the-hanger and thereby raise the bobbin from. its driving engagement with the drum. In this position, the ends of the threads may be pieced up if they have become broken. and the. lever may be swung rearwardly to permit the hanger to again drop down to bring the bobbin into driving engagement with the drum.

If it be desired to doif'the bobbin, the

"lever 31 is swung to the limit of its forward movement. and during this movement the pin33 willlift both members of the'hanger together and the pin 34 will swing the catch 24% to release the free end of the gudgeon 20. The gudgeon carrying member of the holder may then be lifted away from the other member a sufficient distance to permit the bobbin to clear the said other member when being dofi'ed from the; gud

geon, It will hold the gudgeon carrying member'in its raised position until the member-is again swung. downwardly into engagement 'wlth the other member of thehanger.

If so desired, the under side of the arm 13 may be provided with recess36 for receiving the pin when the lever has been swung a sufiicient distance forwardly to will be understood thatthe' spring 28" raise "the hanger sufficiently to causei the bobbin to clear its drum, V

An adjacent recess 371 may also be provided for receiving the piny33 when the lever is swung into position'to operate the tial to the operationfof the device for the piecing up might just as well befaccom-.

pli'shd'when the lever is moved to the limit of its forward movement as when "in: an intermediate position.

It will-be seen from the above description that by dividing the bobbin hanger, the gud geon may be permanently carried by one of the members thus eliminating all liability the dofiing of the spindle.

of dropping or losin'gthe gud geon during;

It will also be seen that a very rapiddofling and replacement of the bobbins may catch to release the free end of the-ggud geon. However, the recess-36 is notessen f be accomplished and also that the peculiar construction of the members of the hangeror permit the utilization of a single lever" ra sing the members together to permit the piecing up of thethr'ead'when so desired} It is evident that slightchanges may be resorted to inthe form, construction and arrangement of the several parts-without departing from'the spirit and scope of'myin vention; hence I do not wish to limit myself strictly to the structureherein set forth, but 7 r What I claim is 1. Ahanger for bobbins comprising-two separable members, bobbin gudgeon se cured to one member, .a catch on the "other member for removably engaging thefree end of'the gudgeon and a single operatinglever for controlling the movement of the mem-j' bers into and out of the bobbin. winding position and also the releasing of the catch to permit the separation of the members for dofiing the bobbin.

2. A hanger for bobbins comprising two separable members, a bobbin gudgeon rotatably secured to one member, a catch on the other member for removably engaging the free end of the gudgeon, a single operating lever for controlling the movement of the members into and out of the bobbin winding position and also the releasing of the catch to permit the separation of the members for dohing the bobbin, and a spring arranged to yieldingly hold the members in the bobbin Winding position and also to yieldingly hold the members in their separated position.

3. A hanger for bobbins comprising two separable members hinged along a common axis, a bobbin gudgeon secured to one member, a catch on the other member for removably engaging the free end of the gudgeon, and a single operating lever for controlling the movements of the members into and. out of the bobbin Winding position and also for releasing the catch to permit the separation of the members for dofling the bobbin from the gudgeon.

4. A hanger for bobbins comprising two members hinged along a common axis, said members overlapping each other, a lever engaging one member for moving both members out of the bobbin winding position and a spring engaging the other member for moving both members into the bobbin winding position when released by the lever, the spring engaged member being separable from the lever engaged member to permit the doffing of the bobbin.

5. A hanger for bobbins comprising two members hinged along a common axis, said members overlapping each other, a lever engaging one member for moving both members out of the bobbin winding position, a spring engaging the other member for moving both members into the bobbin winding position when released by the lever, the spring engaged member being separable from the lever engaged member to permit the dofling of the bobbin, and a gudgeon secured to the spring engaged member.

In testimony that I claim the foregoing as my invention, I have signed my name this 7th day of June, 1915.
